Implicit calls to ListKeys?

I see it more than once on Console and the Debug output window (Visual
Studio). Is there a retry involved or some other reason that it would be
called multiple times?

ListKeys is only invoked during RiakClient.ListKeys,
RiakAsyncClient.ListKeys, RiakClient.DeleteBucket, and


If you're seeing this 2 more times, it could happen because the warning is
issued on both the Trace, Debug, and Console -

There must be another. I am only calling ListKeys and DeleteBucket. Each
once, so I expect to see this warning twice. Which I do most of the time.
But occasionally I see this warning 2 or 3 more times.  Is it possible that
there is some kind of recursion going on that triggers this call?

Hey Kevin,


It looks like only RiakClient.ListKeys(), RiakClient.ListKeysStream(), and
RiakClient.DeleteBucket() will give you that warning. 
You shouldn't see it popup from anywhere else in CorrugatedIron.

One more question I have some code that specifically lists the keys in a
bucket. I am using Corrugated Iron so I get the warning:


*** [CI] -> ListKeys is an expensive operation and should not be used in
Production scenarios. ***


Then because again this is a test/development environment I am explicitly
removing the bucket. I get this same warning again and from what I
understand this is to be expected.

So I run this code with different data sets and every once and a while I get
two or three of these warnings again. Other than ListKeys and DeleteBucket
what other calls in CorrugatedIron implicitly call ListKeys and would
trigger generating this warning again?
